关于英语句子中加不加“s”的问题和三单形式在那些句子中动词要加s（问句或陈述）或不加,在解释一下三单行式与句子加不加是s的关系,要详细的说明和举例!

你讲的大概是两个问题：
1.只有第三人称单数做主语的时候,谓语动词要加s,其他人称不加.
He likes music.
We/I/They/You like music.
2.只有在一般现在时态中,才会出现第三人称单数做主语时动词加s.其他时态不加.如
He is playing basketball.(这里用的现在进行时,动词用be + 现在分词）
He got up early this morning.(一般过去时）
3.另外,表示否定或者疑问助动词要用does,而不是do.
Does he like music?
He doesn't like music.
Do you like music?
I don't like music.
